lTo all whom t may concern.'

Be it known that we, WILLIAM A. Wauw B1NE,EDwARD'LUsTE-NADER, and ROBERT F. LUSTENADER, citizens of the United States, residing at New York, borough of Queens, in the county of Queens and IState of New York, have invented a new and useful Oil Burner, of which the following is a specif.

cation.

This invention-relates to oil burners; and especially to that class adapted to vaporize theoil and burn the same mixed with air; and the objects of our invention are: to provide for the vaporization of any kind oi burnable oil by the heating of the vaporzers with an impinging flame forming a part of the volume of fiame'used for other' purposes in addition to other methods of heating the several vaporizers; to' provide means to place oil in the vaporizers at each end; to provide a number of vaporizers Jfor the proper production of the vapor and the proper commingling of air therewith; and, to provide an air control for the vaporized oill rlhe invention is illustrated in the accompanying drawing, in which- Fig. 1,- is a plan view of an oil burner constructed .in accordance with our invention;

Fig. 2, is a sectional View, illustrating a. mode of application;

Fig. 3, is a plan view of a portion of a coup e of vaporizers, showing a modified form of construction; and,

Fig. 1, is a sectional view of the vaporizers shown in `Figure 3.l

ln the drawing, like numerals of reference refer to the same parts in each of lthe views.

ln practice we provide anoil burner 5, preferabiy enclosed with a removable casing 6 so ready access can be had to the vaporizer for the purpose of cleaning, or for any other purpose.

The burner 5 is preferably made .up of a number of vaporizers, or vaporizing troughs 7, which4 are so constructed andV mounted that a portion 8 projects over aportion of side 10; and air coming from the blower l1 will pass upward from beneath the troughs, and will commingle and support combustion ol the vaporized oil before the flame has ascended above the side 8, thereby heating the entire trough, or vaporizer by conduction, as will be understood. To further the mixture of the air and vaporized oil we bevel the edge of the side 10, as shown at 12. flhis makes a sharp edge 13 on each vapormmg trough over which the air must pass to commingle with the vapor, as will be clear; and this sharp edge seems to work for a more intimate mixtureA of the air and vapor than would occur if there was any thickness of metal between the ascending air andA the ascending vapor.

To further break up the air, we have provided the illets 111 between the troughs. These fillets may be integral, as shown, or may be inserted pieces, as will be clear; .but

-by providing obstructions ot this' kind at intervals the air is divided, and currents are provided which seemto enter the vapor of the oil more thoroughly thereby producing better combustion.l llt will be noticed, too, that by providing the beveled edges 12, we are able to mount the vaporizing troughs in close proximity thereby providing for a certain amount of heat for each vaporizing trough from the radiant heat transmitted by the next vaporizing trough','as' will be clear. ln operation, air ascends from the blower 11, through the pipe 15 into the chamber 16, where it is divided and ascends between the various vaporizing troughs 7. The oil is admitted at each end of each vaporizing trough through the respective valves 17 and 17', so thattroughs of considerable length can be,fused, and the oil 18 will be evenly distributed in each trough, as the oil can have time to meet before being vaporized. rlhus, the vapor will arise throughout the entire length or each trough, as will be clear; and the air ascending from the blower will thoroughly commingle with this vapor, as will be understood; The obstructions, or fillets 14 further assist in thoroughly commingling the vapor, and air, and the airy passing between the vaporizers will be heat,

.tensity of heat within this combustion chamber.

Oil isadmitted to the troughs, and when i yevenly distributed in the troughs, 'is ignited.

The blower isthen started, or the air is turned on through the valve 20, when a flame will soon develop that is substantially free fromy soot, and intensel in its heating qualities. 'After the combustion has fully started, the oil will belvaporized and will burn ina manner, as described above, to keep the several vaporizing troughs hot enough to continue to vaporize the oil, even' although of a very heavy consistency and the vaporizers will be kept below the melting point.

It will thus be seen that we have provided anjoil burner that is cheap `to manufacture, and eilicient in use.

In Figures 3 and 4 we have shown a modied form of construction in which the troughs 7 are used without the fillets; but in this construction the troughs are tilted, as described above, so the higher side will project over a portion -of the bottom.- 9. Thus, the burner 5 will act efficiently even with the fillets omitted. We claim:

. l. In an oil burner, a plurality ofvaporizers spaced apart and means to pass air between them, each vaporizer having an open top whereby a trough is formed throughout its extent adapted to receive the oil being vaporized, said vaporizers being ltilted wherebyl each has a portion thereof projecting over the bottom of the trough against which the flame is\adapted to beat thereby providing supplementary means for heating the vaporizer, forthe purpose set forth.

2. In an oil burner, a plurality of vaporizers mounted in close proximity, each vaporizer having an open top whereby a trough is formed adapted to receive the oil being vaporized, the vapor being free' to rise throughout the length of each vaporizer, one side of each vaporizer having a portion thereof projecting over the bottom of the trough, and the other side having a comparatively sharp edge, and means to force air upward between the troughs.

3. In an oil burner, a plurality of vaporizeis mounted in close proximity, each vaporizer having an open top whereby atrough is formed adapted to receive the oil being vaporized, one side of each vaporizer havling a portion thereof projecting over the botjoined together with fillets at a plurality of points, each vaporizer having anopen top whereby a trough is formed adapted to receive the oil being vaporized, one side of each vaporizer having a portion thereof projectingover the bottom of the trough, and the other vside having a comparatively sharp edge, means to force air upward between said trough, and means to regulate the flow of oil to said' troughs.

5. In an oil burner, a vaporizer U-shaped in form having one side thereof projecting over a portion of the bottom of the trough, the other side having a beveled edge, and means to admit air to the vaporized oil along said beveled edge vprior to the ascension of the ame above said projecting portion whereby the vaporizer is heated.

6. In an oil burner, a plurality of vaporizers, each U-shaped in form having one side of each projecting over a portion of the bottom of the trough, the other edge of each vaporizer being beveled, and means to admit air to the vaporized oil along the beveled edge of each trough prior to the ascension of the flame above said projections whereby the vaporizers and air are heated, for the purpose set forth.

7. In an oil burner, a casing having an open top, a plurality of vaporizers mounted in said open top, each vaporizer being U- shaped in form in cross section and mounted in a tilted manner whereby one edge of each vaporizer is higher than the other-the lower edge being beveled, means to force air in a controlled manner between said vaporizers past said beveled edges into the vaporized oil prior to the ascension of the same above the higher edge of each vaporizer, and means to admit oil to each vaporizer at each end.

8. The herein described oil burner comprising a casing through which air may be passed. a plurality of vaporizers mounted in said casing. each vaporizer being U-shaped in form` and tilted whereby one edge is higher than the other` the lower edge being beveled. means to force air past said vaporizers in a controlled manner, and means to admit oil to each end of each vaporizer.

9. An oil burner comprising a plurality of vaporizer-s spaced apart, each vaporizer comprising an open trough whereby vaporized fluid is free to rise therefrom throughout its length, each trough being tilted whereby one side thereof is higher than the other and projects in a vertical plane over a portion renee of the bottom of the trough, d means to force air upward between the troughs.

l0. An oit burner comprising o plnrellity ot generating troughs forming veporizers spaced apart, the vapor being tree to rise from each trough throughout its length, each trough being tilted whereby one side thereot is higher than the other :rnd 'pro'eots in e v verteel pleno over ar. portion of e bottom ot the trough; end Ineens to torce oir utpwerdbetween seid` troughs-the lower edge of each trough being beveled whereby s'peee is provided for the ascending mir with the vtroughs. mounted close together.
